Abstract
Disc erecting tools under the shaftless inland waters guide bearing of a kind of franc turbine, comprise gripper shoe and screw rod, described gripper shoe comprises front-end and back-end, and rear end is fixedly connected on the end face of front end, two ends on the end face of front end are fixedly connected with a nut respectively, in nut, screw is installed, the end face of front end is also provided with through hole, described screw rod is positioned at this through hole, screw rod is provided with hoisting nut, the utility model provides the erecting tools of disc under the shaftless inland waters guide bearing of a kind of franc turbine, the conventional method of disc under alternative installation water pilot bearing, the security reliability that under guarantee water pilot bearing, disc is installed, increase work efficiency.
Description
Technical field
The utility model relates to disc erecting tools under the shaftless inland waters guide bearing of a kind of franc turbine.
Background technology
Under the shaftless inland waters guide bearing of power station Gou PITAN power station, disc structure as shown in Figure 3, needs to install the sealing of O type and leveling during installation.Under water pilot bearing, the installation conventional method of disc is at lower disc underlay flitch, after adjusting the level of lower disc, height, installs connecting bolt.Because lower disc lower surface is on-plane surface, and disc is divided into pintongs installation usually, and under using flitch leveling, disc is more difficult, inefficiency, the straight line duration that impact is installed.Meanwhile, because lower disc weight is comparatively large, during installation, environment space is relatively narrow and small, and the staff of needs shows many, not only wastes time and energy with this installation method, also easily causes the generation of security incident.
Summary of the invention
The technical problems to be solved in the utility model provides the erecting tools of disc under the shaftless inland waters guide bearing of a kind of franc turbine, the conventional method of disc under alternative installation water pilot bearing, the security reliability that under guarantee water pilot bearing, disc is installed, increases work efficiency.
In order to solve the problem, the technical solution of the utility model is: disc erecting tools under the shaftless inland waters guide bearing of a kind of franc turbine, comprise gripper shoe and screw rod, described gripper shoe comprises front-end and back-end, and rear end is fixedly connected on the end face of front end, and the two ends on the end face of front end are fixedly connected with a nut respectively, in nut, screw is installed, the end face of front end is also provided with through hole, and described screw rod is positioned at this through hole, and screw rod is provided with hoisting nut.
Further, the thickness of described rear end is less than the thickness of described front end.
Further, the cross sectional shape of described gripper shoe is " Z " font.
The technique effect after this structure is adopted to be: to utilize screw rod and hoisting nut can regulate the height of disc, utilize the nut in front end surface and screw can carry out radiai adjustment to disc, wherein the thickness of rear end is less than the thickness of front end is lower end because being inserted into disc for convenience, and then just can adjust the height of disc without the need to cushioning flitch; The cross sectional shape of gripper shoe is " Z " font, the mating shapes of this shape and disc lower surface, and the security reliability that under guarantee water pilot bearing, disc is installed, increases work efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the utility model perspective view,
Fig. 2 is the utility model front view in use,
Shown in Fig. 3 is be mentioned to the front view with during flitch adjustment disc in background technology.
Detailed description of the invention
In order to the progress that those skilled in the art can be made better to understand the utility model hinge structure, before the utility model is elaborated, first be described further to by the method for operating of flitch adjustment disc 4 mentioned in background technology, as shown in Figure 3, general disc 4 adopts split-type structure, usually 4 lobes are divided into, in a pre-installation, must first O RunddichtringO 5 be enclosed within main shaft 8, then 4 distinguish of disc 4 are being loaded onto, and on pad, flitch 7 supports below disc 4, adjust the level of disc 4, after height, connecting bolt 6 is installed, because the weight ratio of disc 4 is heavier, and the lower surface of disc 4 is not plane, so more difficult in adjustment level, during installation, environment space is also relatively narrow and small, several staff is needed to operate, flitch 7 is generally adopt the mode of piling up padded simultaneously, therefore flitch 7 is also very easy to topple over, cause security incident.
Below the utility model is described in detail: as illustrated in fig. 1 and 2, disc erecting tools under the shaftless inland waters guide bearing of a kind of franc turbine, comprise gripper shoe 1 and screw rod 2, described gripper shoe 1 comprises front end 11 and rear end 12, and rear end 12 is fixedly connected on the end face of front end 11, two ends on the end face of front end 11 are fixedly connected with a nut 3 respectively, screw 31 is installed in nut 3, the end face of front end 11 is also provided with through hole, described screw rod 2 is positioned at this through hole, and screw rod 2 is provided with hoisting nut 21.
Further, the thickness of described rear end 12 is less than the thickness of described front end 11.
Further, the cross sectional shape of described gripper shoe 1 is " Z " font.
Using method: because lower disc 4 is splitted structure, be usually divided into 4 lobes, under therefore needing 8 cover water pilot bearings, disc 4 erecting tools is with the use of completing.During installation, first screw rod 2 is installed, again gripper shoe 1 is arranged on screw rod 2, gripper shoe 1 holds up disc 4, the height of disc 4 is adjusted by the hoisting nut 21 below gripper shoe 1, make disc 4 be close to main shaft 8 by the adjustment of nut 3 and screw 31, during guarantee mounting and adjusting, sealing ring 5 does not come off, and realizes adjusting the radial direction of lower disc 4; Finally at installation disc 4 shop bolt and assembling bolt, complete the installment work of disc 4 under water pilot bearing.
